all cars vary, but when i fitted mine the main difference i noticed was 4th gear+ was much quicker through the revs imo , oh and was dam loud with just a backbox!

Got mine put on the Valver a few months back. You wont notice anythin in the low gears but it does seem to be qiucker after 3rd gear. Its is louder too

I wouldnt say it makes any difference to speed imo, just feels a lot nicer to drive. Revs free-er, runs a lot better from cold etc.

Will a new car like a Cup failed an MOT badly without one?

 

[Lunner]

yes, very very rare that you will pass an MOT wiht one on.

I can do you a brand new mild steel de-cat for your valver for £35 delivered if you are interested, sold sh*t loads to folks on here

Proven 3bhp by renault. Very early 16vs non cat made 140bhp.

True, true. The foreign markets had valvers a year earlier than us, pre-cat cars they were.

Well if anyones interested, my Clio turbo, with no cat (and no silencers come to think of it!) just sailed through the emissions test...

I find the Williams is to loud for my liking with a de-cat pipe in,especially for the back seat passengers!,Frees up a bit of power,but takes away a tiny bit of low down respose at the same time.Will consider getting a silenced de-cat though,maybe later this year.

pound for pound probably the best performance mod i have done to my RT, fifth gear actully makes me go somewhere now and isnt just a fuel saver gear !

i agree with most of the above comments!......

very loud, feels like it revs easier, maybe a little slower early gears but i think u can notice a slight difference in high gears/motorway driving!

dont worry about mot, its only once a year!
